I have had a problem in recompiling gimp24 with the new png 1.2.9. Some 
functions of libpng used in Gimp like "png_write_destroy" are local in 
the new libgimp12 and global in (the backward-compatible ?) 
libpng.so.3.9.0, as they were in png 1.2.8 and before:

nm /usr/pkg/lib/libpng12.so | grep write_destroy
0001195c t png_write_destroy

nm /usr/pkg/lib/libpng.so.3.9.0 | grep write_destroy
00013b9c T png_write_destroy

And that causes a Gimp build failure. I had to manually patch libpng.so 
to make it point towards libpng.so.3.9.0.

I have done something wrong, or is this a *real* problem?
